Jerry –
I’ve been using 10KW inverter before and it was great, but with only 2 MPPTs, it couldn’t handle more panels. The 12KW version has 4 MPPTs, so I only needed one instead of two smaller units. Super happy with this all-in-one system!
Edward –
I’ve installed a lot of systems over the years, including the EG4 12KW inverters, but this EGBATT 12KW 18KPV Hybrid Inverter honestly performs better. The extra MPPT input makes a big difference when working with multiple roof angles, and the overall build quality feels solid. What really stands out is the factory-direct pricing . very reasonable for the features and performance you get. It’s efficient, easy to set up, and runs smoothly. Definitely one of the best 12KW hybrid inverters I’ve used. Highly recommended.
